I just reflashed back to OEM and the car runs unbelievably well. I was beating the pants off of Porsches at a PCA event. For unknown reasons discussed earlier in this thread, my car lost power from the tune and driveability suffered significantly. Maybe my car was the oddball but it's got plenty power through the band now.
Gluck and cheers. As always evolve has been very timely in their responses and have helped me in all the ways they could.
